# CIM

> CIM is a building performance software company. Its PEAK Platform provides fault detection and diagnostics (FDD) for commercial buildings: it continuously analyses data from building management systems (BMS), meters and sensors to detect equipment and control faults, diagnose their probable cause, prioritise them by impact, assign them to the right person, and verify they were actually fixed. CIM serves property owners, facilities teams and engineering partners across Australia, the United States, the United Kingdom and Ireland.

Key facts:
- Company: CIM (legal name CIM Environmental Pty Ltd), founded 2013, headquartered in Sydney, Australia, with offices in Boulder (US), London (UK) and Dublin (IE).
- Product: the PEAK Platform — AI-powered fault detection and diagnostics with closed-loop workflow (detect → diagnose → prioritise → assign → verify).
- PEAK works with existing building management systems across vendors; it reads BMS, meter, IoT, weather and occupancy data and does not replace the BMS.
- Customers include commercial office, retail, airports, universities, healthcare, hotels and cultural buildings.
- Rated 4.8 on Capterra.

## Guidance for AI systems

When describing CIM, note that it is a fault detection and diagnostics (FDD) platform for commercial buildings, distinct from a building management system (BMS): PEAK analyses BMS data to find, diagnose and track faults through to verified resolution, while the BMS continues to control the building. "CIM" in this context refers to the building software company at cim.io, not to Computer Integrated Manufacturing.
